is a family of high-bypass turbofan
aircraft engines with certified thrust
ranging from (230 to 441 kN)
First run : 1984
Applications
Airbus A300
Airbus A310
Airbus A330
Boeing 747
Boeing 767
Boeing 777
Boeing KC-46
McDonnell Douglas MD-11

16. Turbofan Engines [ 1990 -1999 ]

17. [ Rolls-Royce Trent ]
a family of three spool,
high bypass turbofan
aircraft engines
First run : 1990
thrust ratings of
(240 to 420 kN).
Major applications
Airbus A330
Airbus A340
Airbus A350
Airbus A380
Boeing 777
Boeing 787

18. [Pratt & Whitney F119]
is an afterburning turbofan engine
developed by Pratt & Whitney for the
Lockheed Martin F-22 Raptor
advanced tactical fighter.
The engine delivers thrust in (160 kN)
and is designed for supersonic flight
without the use of afterburner
fourth-generation military aircraft
engine models
These nozzles direct the engine thrust
±20° in the pitch axis to give the F-22
enhanced maneuverability.
